PETER B. OUPP, OF VAN WERT, OHIO.

COMBINED PLATFORM-ROCKER AND RECLINING-CHAIR.

SPECIFICATION forming part of Letters Patent No. 296,931, dated April15, 1884. Application filed July 19,1883. (ModcL) T0 on whom it mayconcern:

Be it known that I, PETER B. GUPP, of Van Wert, in the county of VanWert and State of Ohio, have invented a new and Improved CombinedPlatform-Rocker and Reclining- Ohair, of which the following is a full,clear, and exact description.

My invention is an improvement in the class of platfbrm-rockers; and theimprove ment is embodied in the construction and corn bination of partsas hereinafter described and claimed.

Reference is to be had to the accompanying drawings, forming part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure 1 is a perspective view of my improved combined rocker andreclining-chair, the upholstering being removed. Fig. 2 is alongitudinal sectional elevation of the same. Fig. 3 is a detail sideview of the rear part of the arm-rests.

The seat-frame A is provided with rockers B, resting on a base-frame, O,and held on the same by suitable springs, D, in the usual man ner. Theback frame, E, is hinged to the rear part of a seat, F, which slides ingrooves formed in the inner. sides of frame A. The back E has lateralstuds G, whose enlarged or flanged heads enter undercut slots H in thearms J of the seat-frame A. These studs assist in supporting the arms Jagainst outward pressure by holding them connected with the The slots Hare closed at their ends, so that the studs G may limit the adjustmentof the seat and back in both directions. A rack, K, is secured to theunder side of the sliding seat F, and engages with a pinion, L, mountedrigidly on a transverse shaft, M, j ournaled in the rocking seatframe A,and provided at one end with a handle or disk, and having the other endsquared. A longitudinally-slotted plate, N, having one end forked, andhaving the'other end bent up to form a handle, is held on one side ofthe seat-frame by a screw or headed stud. The forked end of said plateis adapted to engage with the squared end of shaft M, and thereby tolock the same so that it cannot rotate. By this means the seat F and itsattached back may be held fixed in any adjustment.

The chair is adjusted in the following manner: If the sliding seat F ismoved toward the front end of the chair, by turning the shaft M, theupper end of the back frame will be moved downward and the lower endforward, and the inclination of the back frame will be less. If the seatis moved backward, the back frame will be swung upward or raised. Theseat and back can thus be adjusted, and the person occupying the chairneed not leave it while it is being adjusted. The chair can always berocked in whatever position the seat and back frame may be. Before theshaft M can be turned, the latch-plate N must be withdrawn from thesquared end of the shaft, so that the squared end of the shaft will beout of the forked end of the latch-plate. the chair has been adjusted,the latch-plate is pushed back, so that the squared end of the shaftwill be between the shanks of the fork in the plate N, whereby the shaftM is prevented from revolving and the back frame is held at the desiredinclination.

In adjusting the seat, the limits of its movement are determined by theclosed ends of the slots H, which, in practice, is an importantfunction;

I do not claim, broadly, a chair-seat which is adjusted by rack andpinion, nor one having a back hinged thereto, since I am aware these arenot new.

I do not abandon or dedicate to the public any patentable feature setforth herein and not hereinafter claimed, but reserve the right to claimthe same eitherin a reissue of any patent that may be granted upon thisapplication or in other applications for Letters Patent that I may make.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

The combination of the following elements: the seat-frame A, having sidegrooves and arms provided with closed slots H, the sliding seat F,having rack K, the hinged back E, having studs G, projecting laterallyinto'said slots, the rotatable pinion-shaft M L, having a squared end,and the forked sliding plate N, arranged as described, to lock saidshaft, all as hereinbefore set forth.

PETER B. OUPP.
